getPathWithoutSchemeAndAuthority

mergePaths

Merge 2 paths such that the second path is appended relative to the first.
The returned path has the scheme and authority of the first path. On
Windows, the drive specification in the second path is discarded.

isUriPathAbsolute

isAbsolute

There is some ambiguity here. An absolute path is a slash
relative name without a scheme or an authority.
So either this method was incorrectly named or its
implementation is incorrect. This method returns true
even if there is a scheme and authority.
